PE

Product Description

Polyethylene (polyethylene, PE) is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of alpha-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest use temperature can reach -100 ~ -70 ° C), good chemical stability, can resist the erosion of most acids and bases (not resistant to acids with oxidizing properties). Insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation.

 

PE is sensitive to environmental stresses (chemical and mechanical), and heat aging resistance is poor due to the chemical structure and processing bars of the polymer. Polyethylene can be processed by the same molding methods used for general thermoplastics. It has a wide range of uses, mainly for the manufacture of films, packaging materials, containers, pipes, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulating materials for television, radar, etc. With the development of petrochemical industry, polyethylene production has been rapidly developed, and the output accounts for about 1/4 of the total output of plastics.
